🚨 Critical Warning
The frequency and severity of AI-related sanctions are increasing rapidly. Courts are becoming less tolerant of AI mistakes as awareness grows. What might have received a warning in 2023 now results in significant sanctions in 2024.
🛡️ How to Avoid These Mistakes
Based on analysis of sanctioned cases, here are the most effective prevention strategies:
✅ Always Verify AI Output
Independently verify every fact, case citation, and legal claim generated by AI. Treat AI as a first draft that requires thorough fact-checking and legal review.
✅ Never Skip Human Review
Require attorney review of all AI-generated content before filing or client communication. Document your review process and findings.
✅ Understand AI Limitations
Know that AI can hallucinate facts, create false citations, and misunderstand legal concepts. Use AI as a research starting point, not an authoritative source.
✅ Protect Client Confidentiality
Never input confidential client information into public AI tools. Use enterprise-grade AI solutions with proper data protection agreements.
✅ Maintain Professional Standards
AI doesn't change your ethical obligations. Continue to provide competent representation, maintain confidentiality, and supervise all work product.
✅ Document Your Process
Keep records of how you use AI, what verification steps you take, and what human review occurs. This documentation can be crucial if questions arise.
